The present Application for Patent claims priority to International Patent Application No. PCT/US2016/065206 to Arndt et. al., titled “SUSPENDED CANOPY SUPPORT STRUCTURES”, filed Dec. 6, 2016, assigned to the assignee hereof, which is hereby incorporated by reference in its entirety.

BACKGROUND

Conventional pole-mounted canopy support structures suffer from an inability to independently configure the structure's height and span. In particular, the structure has to be tall enough that the structure's retractable arms can close without hitting the ground or other objects. Conversely, limits on the practical height of the structure limit the span of the structure's extended arms. Further, the supporting pole must be mounted in a stable way in order to properly support the canopy when in retracted and extended position. Opportunities exist for improvements in canopies and canopy support structures.

SUMMARY

In one embodiment, a canopy support structure in accordance with the present disclosure includes a plurality of hubs arranged in series, and a plurality of articulating arms connecting the plurality of hubs. At least one of the plurality of hubs includes a suspension interface for suspending the canopy support structure from a support member. At least some of the plurality of hubs are movable toward and away from each other to operate the canopy support structure between expanded and retracted positions. The plurality of articulating arms include a plurality of primary ribs connected directly to the plurality of hubs, a plurality of secondary ribs connected to some of the plurality of primary ribs, and a plurality of tertiary ribs coupled between the plurality of secondary ribs and other of the plurality of primary ribs.

Moving at least some of the plurality of hubs toward each other may move the canopy support structure into the expanded position. Moving at least some of the plurality of hubs away from each other may move the canopy support structure into the retracted position. The plurality of hubs may include at least a first hub and a second hub, wherein the first hub is positioned vertically above the second hub, and the first hub is connected to the support member via the suspension interface to suspend the canopy support structure. The plurality of hubs may include at least a first hub and a second hub, wherein the first hub is positioned vertically above the second hub and the second hub is connected to the support member via the suspension interface to suspend the canopy support structure.

The plurality of hubs may include at least first, second and third hubs, wherein the second hub is positioned in series between the first and third hubs, and the first hub, the second hub, or the third hub is connected to the support member via the suspension interface to suspend the canopy support structure. The canopy support structure may also include a mounting connector that extends through the first and second hubs and includes a first end connected to the support member and a second end connected to one of the first, second and third hubs.

The support structure may include a track. The support structure may include a pivot support operable to move the canopy support structure into angled positions with respect to a vertical direction. The support structure may include a single ground support offset from a geometric center of the canopy support structure. The canopy support structure may rotate about a vertical axis within the ground support.

In another embodiment, a canopy support structure includes an upper hub, an intermediate hub, a lower hub, and a plurality of articulating arms connecting the upper, intermediate and lower hubs. The upper, intermediate, and lower hubs are arranged in series with the upper hub being positioned vertically above the intermediate and lower hubs. Moving the intermediate and lower hubs axially relative to each other moves the canopy support structure between expanded and retracted positions. One of the upper, intermediate and lower hubs is configured to be connected to a support member arranged above the canopy support structure.

The plurality of articulating arms may include a plurality of primary ribs connected directly to the upper, intermediate, and lower hubs, a plurality of secondary ribs connected to some of the plurality of primary ribs, and a plurality of tertiary ribs coupled between the plurality of secondary ribs and other of the plurality of primary ribs.

Another embodiment is directed to a canopy support structure that includes a set of primary hubs arranged in series about a common axis, at least one set of secondary hubs arranged radially relative to the set of primary hubs, and a plurality of articulating arms connecting the primary and secondary hubs.

DETAILED DESCRIPTION

The present disclosure is directed to canopy structures and related methods of use. The canopy support structures may support a canopy such as a fabric sheet. The canopy may be directly connected to the canopy support structure such that opening and closing the canopy support structure moves the canopy between retracted and extended positions (e.g., to vary an amount of shade provided by the canopy). The canopy support structure and canopy together may define a canopy, umbrella, or similar shade producing structure.

One aspect of the present disclosure is directed to a canopy support structure that has a relatively compact construction. The canopy support structure may have reduced space requirements for storing and/or operating the canopy support structure between extended and retracted positions. Another aspect of the present disclosure relates to a canopy support structure that may be suspended from a support member positioned above the canopy support structure. A still further aspect of the present disclosure relates to a canopy support structure that may be supported from above the canopy support structure. In some embodiments, the canopy support structure may be supported on a support pole that extends through or is connected to one or more hubs of the canopy support structure. Some embodiments of the canopy support structures disclosed herein may be referred to as “poleless” canopy support structures, or top support canopy structures, or suspended canopy support structures.

The canopy support structures disclosed herein may have different shapes and sizes. An example canopy support structure may have a general square shaped perimeter, a hexagonal shaped perimeter, or a generally circular shaped perimeter formed by a generally radial arrangement of multiple articulating ribs. The canopy support structure may have a single set of hubs from which a plurality of primary, secondary and/or tertiary ribs are supported. The ribs may also be referred to as arms or articulating arms. In other embodiments, the canopy support structure includes a plurality of sets of hubs, including a primary set of hubs arranged centrally, and a plurality of secondary sets of hubs positioned radially outward from the primary set of hubs and interconnected with the various primary, secondary and/or tertiary ribs, and/or ribs arranged radially and in other orientations (e.g., tangentially).

FIGS. 1-3 illustrate a first example of a canopy support structure 100. The canopy support structure 100 comprises first, second and third hubs 102, 104, 106 and a plurality of primary, secondary and tertiary ribs 108, 110, 112, respectively. The hubs 102, 104, 106 are interconnected with each other via the ribs 108, 110, 112. As the hubs 102, 104, 106 move toward and away from each other, the ribs 108, 110, 112 move between retracted and extended positions. When a canopy is mounted to the canopy support structure 100, moving the ribs 108, 110, 112 between extended and retracted positions varies an amount of shade provided by the assembly of the canopy support structure 100 and the canopy.

FIG. 1 shows the canopy support structure 100 in a fully extended position. FIG. 2 shows the canopy support structure 100 in an intermediate extended/retracted position, also referred to as a partially extended or partially retracted position. FIG. 3 shows the canopy support structure 100 in a fully retracted position.

The first, second and third hubs 102, 104, 106 are arranged in series with each other. The first hub 102 is positioned vertically above the second hub 104. Second hub 104 is positioned vertically above the third hub 106. In one embodiment, the first hub 102 is connected to a suspension support member 120 with a mounting connector 118. A hub connector 124 may provide a connecting interface between the mounting connector 118 and the first hub 102. The hub connector 124 may be referred to as a suspension interface for connection of at least one of the hubs 102, 104, 106 to suspension support member 120. The hubs 102, 104, 106 may include other features, such as apertures, mounting brackets, mounting connectors (e.g., mounting connector 118) and the like that may be considered a suspension interface for connection to a support member. The first hub 102 maintains substantially the same vertical position while the canopy support structure 100 is operated between the fully extended position shown in FIG. 1 and the fully retracted position shown in FIG. 3. The canopy support structure 100 is extended and retracted by moving the second and third hubs 104, 106 toward and away from each other. The second and third hubs 104, 106 move axially relative to each other along an axis that extends through all three of the first, second and third hubs 102, 104, 106.

In one embodiment, a first draw member 114 is connected to the second hub 104. Pulling downward on the first draw member 114 moves the ribs 108, 110, 112 into the fully extended position shown in FIG. 1. A second draw member 116 may be connected to the third hub 106. Pulling vertically downward on the second draw member 116 may move the first and second hubs 104, 106 away from each other, thereby moving the ribs 108, 110, 112 from the extended position into the intermediate position shown in FIG. 2 and into the fully retracted position shown in FIG. 3. This may be beneficial when trying to close the umbrella during inclement weather conditions such as wind events. When no wind is present, the weight of the umbrella may be sufficient to retract the canopy support structure 100 once draw member 114 is released. Thus, applying a downward force on the first draw member 114 moves the second and third hubs 104, 106 toward each other to open the canopy support structure into a fully extended position, and applying a vertically downward force to the second draw member 116 moves the second and third hubs 104, 106 away from each other thereby closing the canopy support structure 100 into a fully retracted position.

Other arrangements involving single or multiple pulleys in single or multiple locations are possible. For example, a draw member may be attached to second hub 104, extend through a pulley mounted to third hub 106, and back through first and second hubs 102, 104 to another pulley positioned at hub connector 124, mounting connector 118, and/or suspension support member 120. In another arrangement, a draw member may be attached to third hub 106, extend through a pulley mounted to second hub, extend through another pulley mounted to third hub 106, extend to the pulley at the second hub, extend through third hub 106 or down through the pulley at third hub 106 and back up through the first and second hubs 102, 104 to a pulley positioned at hub connector 124, mounting connector 118, and/or suspension support member 120. Many other options are available for placement of pulleys, routing of draw members, and application of pulling forces to any one of the hubs 102, 104, 106 to assist in operating a canopy support member between opened and closed positions.

The first and second draw members 114, 116 may include a strap, cable, rope, cord or other flexible structure. Alternatively, the first and second draw members 114, 116 may comprise a rigid structure such as, for example, a pole, rod, or the like. The first, second and third hubs 102, 104, 106 may each include a pass-through hole 126, 128, respectively. The first draw member 114 may extend through the pass-through hole 128 of the third hub 106. In some embodiments, the first draw member 114 may be directly connected to the second hub 104 and may, for example, wrap around or extend at least partially through the pass-through hole 126. The second draw member 116 may be directly connected to the third hub 106 and may extend through the pass-through hole 128. Alternatively, the first and second draw members 114, 116 may extend along an exterior of the second and third hubs 104, 106 rather than through the pass-through holes 126, 128.

The primary, secondary and tertiary ribs 108, 110, 112 couple together the first, second and third hubs 102, 104, 106. The ribs 108, 110, 112 may include sets of scissor-connected ribs. By “scissor-connected”, it is meant that the ribs are connected at some point along their length to the mechanism, such as a pin or mechanical connector (e.g., pivot-connected sleeves or clips for receiving different ones of the scissor-connected ribs). Each of the hubs 102, 104, 106 is pivotally connected to at least one other of the hubs 102, 104, 106 by a respective set of ribs 108, 110, 112.

The primary ribs 108 may include a first set of primary ribs 108-a, a second set of primary ribs 108-b, and a third set of primary ribs 108-c. The ribs of the first set of primary ribs 108-a each includes first and second ends 130-a, 132-a. The ribs of the second set of primary ribs 108-b each include first and second ends 130-b, 132-b and an intermediate point 134, located between the two ends 130-b, 132-b. The ribs of the third set of primary ribs 108-c each include first and second ends 130-c, 132-c and at intermediate point 136. The first ends 130-a of the first set of primary ribs 108-a are pivotally connected to the first hub 102. The first ends 130-b of the second set of primary ribs 108-b are pivotally connected to the second hub 104. The first ends 130-c of the third set of primary ribs 108-c are pivotally connected to the third hub 106. The second ends 132-a of the first set of primary ribs 108-a are pivotally connected to the second sets of primary ribs 108-b at intermediate point 134 and to the third sets of primary ribs 108-c at the intermediate point 136. This pivot connection point may be referred to as a first rib connection point 156.

The secondary ribs 110 each include first and second ends 138, 140 and an intermediate point 150, located between ends 138, 140. The tertiary ribs 112 each include first and second ends 152, 154. The second ends 132-c of the third set of primary ribs 108-c are connected to the first end 138 of the secondary ribs 110. The second end 132-b of the second set of primary ribs 108-b are connected to the first end 152 of the tertiary ribs 112. The second end 154 of tertiary ribs 112 are connected to one of the secondary ribs 110 at the intermediate point 150. The second end 140 of the secondary ribs 110 is a free end that is not connected to another rib or hub. The free ends 140 of the secondary ribs 110 may be arranged to connect a canopy, canopy sheet, or canopy segment. For example, a canopy or canopy sheet may have pockets that receive the free second ends 140 of the secondary ribs 110 to provide a connection between the canopy support structure 100 and the canopy.

The connecting point between the third set of primary ribs 108-c and the secondary ribs 110 may be referred to as a second rib connection point 158. The connection point between the second set of primary ribs 108-b and the tertiary ribs 112 may be referred to as a third rib connection point 160. A connection point between the secondary ribs 110 and tertiary ribs 112 may be referred to as a fourth rib connection point 162. Each of the connection points 156, 158, 160, 162 is a pivot connection point. A pivot connection point may be defined or provided using, for example, a bypass pin connection. Various types of bypass pin connections may include a pin that extends through respective ribs at the connection point. The pin may be secured by having a head on one end and a flare (rivet), bend, nut, or other feature on its opposite end. In the case of a nut, the pin may be provided with threads over at least a portion thereof. A bushing may be positioned at the rib connection point and may be positioned between ribs at the connection point to provide a separation there between. In other arrangements, the ribs may be in direct contact with each other at the rib connection point. By way of example, the bushings or spacers may be formed of nylon, plastic, steel or the like. Using a lower friction material can improve the operability and extend the life of the ribs 108, 110, 112. In other examples, a mechanical connector connection may be used at the pivot connection point 156, 158, 160, 162. A mechanical connector connection may include a connector of a body in which one or more pins are received. Various other types of connections may be used at any one of the rib connection points 156, 158, 160, 162.

The ribs 108, 110, 112 may be formed using the same or different materials. By way of example, any of the ribs 108, 110, 112 may be hollow extruded aluminum tubes having, for example, square, oval, rectangular, or circular cross-sections. In another example, any one of the ribs 108, 110, 112 may comprise metal cores or fabric cables. In still further examples, any of the ribs 108, 110, 112 may comprise wood or a composite material, may be hollow or solid, or may have any desired cross-sectional shape. Ribs may also be made up of two members sandwiched together. For example, FIG. 17 described below includes third primary ribs that are double members with the second primary ribs sandwiched in between. This arrangement could be reversed. Alternatively, the first primary rib may be sandwiched in between other of the ribs.

A canopy may be connected to the secondary ribs 110 at ends 138, 140 or at ends 138, 140 and intermediate point 150. Alternatively, the canopy may be connected to end 140 and connection point 158 or end 140 and connection points 158 and 162. The canopy may also be connected continually along a custom extruded secondary rib 110 (e.g. a rolled or beaded seam within a continual slot).

The hubs 102, 104, 106 may be formed from a variety of materials. In one example, the hubs 102, 104, 106 are formed as a unitary molded structure. The hubs 102, 104, 106 may have features formed therein for receiving wheels or bearings, single or multiple pulleys, bores for receiving pivot pins, connectors and the like. In some arrangements, the hubs 102, 104, 106 may be constructed of modular components, having, for example, wheels or rollers, pivot connection members, and the like.

The canopy support structure 100 shown in FIGS. 1-3 is supported in a suspension arrangement by connection of the first hub 102 to a suspension support member 120 via the first mounting connector 118. Other arrangements are possible in which the canopy support structure 100 is supported by connecting it to one of the second and third hubs 104, 106. For example, FIG. 5 shows the canopy support structure 100 mounted to the suspension support member 120 by connection with the third hub 106. FIG. 17 shows a suspension support structure 1700 mounted to a suspension support member 1702 by connection with the second hub 104. A mounting connector 506 extends through the first and second hubs 102, 104 and into connection with the third hub 106. The first hub 102 may include a pass-through hole similar to pass-through hole 126 in second hub 104 to provide passage of the mounting connector 506 to the third hub 106.

The plurality of hubs 102, 104, 106 may have a central axis along which one or more of the hubs 102, 104, 106 move. This central axis may be straight or curvilinear. The plurality of hubs 102, 104, 106 may accommodate a radial arrangement of ribs with respect to the central axis. The plurality of hubs 102, 104, 106 may accommodate an arrangement of ribs offset from a radius of one or more of the hubs 102, 104, 106 with respect to the central axis, as shown in FIG. 17. The plurality of hubs 102, 104, 106 may accommodate a combination of radially arranged ribs with respect to the central axis and ribs that are offset from the central axis.

The canopy support structure 500 shown in FIG. 5 may be operated between extended and retracted positions using a pulley 502 and third draw member 504. The pulley 502 may be connected to, for example, the suspension support member 120 or mounting connector 506. The third draw member 504 may be connected at one end to the second hub 104. An opposite end of the third draw member 504 extends through the first hub 102, around the pulley 502, back through the first, second and third hubs 102, 104, 106 and be accessible for pulling downward by an operator. Pulling downward on the free end of third draw member 504 raises the second hub 104 thereby moving the canopy support structure 100 from the fully extended position shown in FIG. 5 to a fully retracted position. The first draw member 114 may be connected to the second hub 104. Pulling downward on the first draw member 114, may move the second hub 104 towards the third hub 106, thereby moving the canopy support structure 500 from a fully retracted position to the fully extended position shown in FIG. 5.

Alternatively, one end of third draw member 504 may be connected to the third hub 106, an opposite end of third draw member 504 may pass through pulley 502 and a second pulley is mounted at a remote location along the length of support member 120. Pulling on the free end of the third draw member 504 from the remote location may move the second hub 104 towards the third hub 106, thereby moving the canopy support structure 500 from a fully retracted position to the fully extended position.

Other pulley configurations are possible for increased mechanical advantage and ease of operation (e.g., one or more draw members anchored at hub 106, passing through a pulley at hub 104, back to a pulley at hub 106, up to the pulley 502, etc.).

The free end of draw member 504 may be secured with a mechanical connector, such as a cleat, to the hub 106 or to a remote location. Alternatively, the free end of draw member 504 may wrap around the shaft of a motor or spindle of a crank assembly at any point along the support member 120.

FIG. 4 illustrates another arrangement for opening and closing the canopy support structure 400. The canopy support structures 400, 500 shown in FIGS. 4 and 5 may be examples of the canopy support structure 100 shown with reference to FIGS. 1-3.

The canopy support structure 400 shown in FIG. 4 includes a pulley 402 mounted to the first hub 102. The canopy support structure 400 is supported from above by the suspension support member 120 via first mounting connector 118 and hub connector 124. A fourth draw member 404 is connected at one free end to the third hub 106. In opposite end the fourth draw member 404 extends through the second hub 104, wraps around the pulley 402, and passes back through the second and third hubs 104, 106 where it is accessible for operation. A user may pull down on the free end of the fourth draw member 404, thereby moving the third hub 106 towards the second hub 104 to actuate the canopy support structure 100 into the fully extended position shown in FIG. 4. The second draw member 116 may also be connected to the third hub 106. Pulling downward on the second draw member 116 moves the third hub 106 away from the second hub 104, thereby moving the canopy support structure toward a fully retracted position. Alternatively, the pulley 402 could be attached to the second hub 104.

The canopy support structure 100 may have sufficient friction or other features provided at the various pivot connection points between the ribs 108, 110, 112 and the hubs 102, 104, 106 such that the canopy support structure 100 maintains a given extended or retracted position, whether fully or partially extended or retracted, without application of an outside force, fastener, or retaining member. In other examples, a fastener, connector, cleat, or the like may be used to hold the canopy support structure in a given extended or retracted position, such as a position obtained by operating any one of the first, second, third and fourth draw members 114, 116, 504, 404, respectively. In still further examples, a crank or motorized assembly may be used to operate the canopy support structure 100 between various extended and retracted positions. A counterweight (preferably one that is remotely installed so as not to add to the load of support member 120) may operate to rise when the canopy support structure 100 is retracted and lower when the canopy support structure 100 is extended.

FIGS. 6 and 7 illustrate another example canopy support structure 600 mounted to a suspension support member 120. The canopy support structure 600 is an alternative structure to other structures disclosed herein in that the first hub 102 and associated ribs 108-a have been eliminated. The canopy support structure 600 includes hubs 104, 106, a set of primary ribs 108-b, a set of primary ribs 108-c, secondary ribs 110, and tertiary ribs 112. Moving the hubs 104, 106 toward and away from each other operates the canopy support structure 600 between the fully extended position shown in FIG. 6 and the fully retracted position shown in FIG. 7.

The canopy support structure 600 may be mounted to the suspension support member 120 with a mounting connector 118, which may be connected to the hub 104 and horizontal member 604 of the suspension support member 120. The mounting connector 118 may extend through the hub 104 and protrude toward hub 106. The protruding portion of the mounting connector 118 may provide a position stop for hub 106 as it moves toward the ccond hub 104, and may provide a relative spacing between the hubs 104 and 106 when the canopy support structure is in the fully extended position shown in FIG. 6. In other embodiments, the mounting connector 118 may be connected to the hub 106 and the hub 104 slides along the mounting connector 118.

The vertical and horizontal members 602, 604 of the suspension support member 120 may move relative to each other to adjust an orientation and/or position of the canopy support structure 600. For example, the horizontal member 604 may rotate about a horizontal axis or rotate about a vertical axis relative to the vertical member 602. In some embodiments, the vertical member 602 may rotate about a vertical axis. In other embodiments, the mounting connector 118 may rotate or pivot relative to the horizontal member 604, or the canopy support structure 600 may rotate or pivot relative to the mounting connector 118.

Referring to FIG. 8, a canopy support structure 800 is shown mounted to a suspension support member 120. The canopy support structure 800 includes a set of primary hubs 102, 104, 106 to which a set of primary ribs 108-a, 108-b, 108-c are connected. The canopy support structure 800 also includes a plurality of secondary sets of hubs 802 that each include a hub 814 and a hub 816. The hubs 814 are connected to the primary hubs 106 with the ribs 108-c. The hubs 816 are connected to the primary hubs 104 with the ribs 108-b. A set of second primary ribs 108-b extend from the hubs 814 and separate sets of third primary ribs 108-c extend from the hubs 816. The secondary sets of hubs 802 may be connected to each other with additional lateral ribs 806. The lateral ribs 806 may provide additional strength and/or stability for the canopy support structure 800, particular when in a partially open position and when operating the canopy support structure 800 in inclement weather conditions such as wind. The lateral ribs 806 may be rigid or flexible. The lateral ribs 806 may optionally be added between any of the hubs 802 to adjust an amount of support/stability desired for any particular design.

The suspension support member 120 includes a vertical member 602 and a horizontal member 604 as described above with reference with FIGS. 6 and 7. The canopy support structure 800 is mounted to the horizontal member 604 by connection to the first hub 102 of the primary set of hubs. A mounting stop 804 may be mounted to one of the second and third hubs 104, 106 of the primary set of hubs. The mounting stop 804 provides a position stop and relative spacing between the second and third hubs 104, 106 when the canopy support structure 800 is in the fully extended position shown in FIG. 8. FIG. 9 shows the mounting stop 804 mounted to the third hub 106 of the primary set of hubs. Alternatively, the mounting stop 804 may be extended to first hub 102. In this arrangement, the mounting stop 804 provides a position stop and relative spacing between the first, second, and third hubs 102, 104, 106 when the canopy support structure 800 is in the fully extended position.

As discussed above, the suspension support member 120 may have various adjustability features, which may be used to move the canopy support structure 800 into different positions and orientations. For example, the horizontal member 604 may rotate about a vertical or horizontal axis, the vertical member 602 may rotate about a vertical axis, and a connection point between the canopy support structure 800 and the horizontal member 604 may include a pivot or rotation connection to provide movement of the canopy support structure 800 relative to the horizontal member 604.

FIGS. 10-12 illustrate another example canopy support structure 1000. The canopy support structure 1000 includes first, second and third hubs 102, 104, 106 that are interconnected with a plurality of primary, secondary and tertiary ribs 108, 110, 112. Some of the primary ribs 108 are connected to a plurality of cross ribs 1002. The cross ribs 1002 may provide additional support and stability for the canopy support structure 1000. In one example the cross ribs 1002 are connected to the third set of primary ribs 108-c at a point where the third set of primary ribs 108-c connects to the secondary ribs 110. The plurality of tertiary cross ribs 1004 may also be used to provide support for the cross ribs 1002. The tertiary cross ribs 1004 may connect to ends of the second set of primary ribs 108-b at a point where the tertiary ribs 112 connect to the primary ribs 108-b.

The canopy support structure 1000 may be mounted to a suspension support member 1006. The suspension support member 1006 includes a support beam 1008, a vertical member 1012, and a brace member 1010. The suspension support member 1006 may be operable between a fully extended position shown in FIGS. 10 and 11, and a retracted position shown in FIG. 12. When in the fully extended position, the canopy support structure 1000 is positioned at a maximum distance away from the vertical member 1012. When in a fully retracted position shown in FIG. 12, the canopy support structure 1000 is positioned adjacent to the vertical member 1012. Typically, the suspension support member 1006 is sized and configured to accommodate the canopy support structure 1000 in its fully extended position shown in FIG. 10 when the suspension support member 1006 is also in its fully extended position. When the canopy support structure 1000 is in a partially or fully retracted position, the suspension support member 1006 may also be operable into partially or fully retracted positions without the canopy support structure 1000 contacting the vertical member 1012.

The suspension support member 1006 may have various features that facilitate movement of the canopy support structure 1000. The extending and retracting position shown in FIGS. 10 and 12 move the canopy support structure 1000 toward and away from the vertical member 1012. The suspension support member 1006 may have other features such as a pivotal connection between the support beam 1008 and the canopy support structure 1000 (e.g. via the rounding connector 118 or some other connection), that provides pivotal movement of the canopy support structure 1000. In another example, the support beam 1008 is able to rotate about a generally horizontal axis or a generally vertical axis. The vertical member 1012 may rotate about a vertical axis. The various features of the canopy support structure 1000 and suspension support member 1006 may provide adjustability of the canopy support structure 1000 into various positions and orientations.

The canopy support structure 1000 may form a generally square or rectangular canopy or umbrella. The generally square or rectangular canopy support structure 1000 or a generally square or rectangular shaped canopy/umbrella may be attached to any overhead support, such as the suspension support member 1006 described with reference to FIGS. 10-12. The canopy support structure 1000 may be mounted to the suspension support member 1006 in any desired manner including, for example, directly connecting the mounting connector 118 to the first hub 102, or providing a connection (e.g. via mounting connector 506 described above) to the second or third hubs 104, 106. A spacer member such as mounting stop 804 may be connected to any one of the first, second and third hubs 102, 104, 106 to provide a position stop and spacing between two or more of the first, second and third hubs 102, 104, 106 to define the fully extended and/or fully retracted positions for the canopy support structure 1000.

FIG. 13 shows the canopy support structure 100 described with reference to FIGS. 1-5 mounted to a suspension support member 1300. A suspension support member 1300 includes a generally vertical member 1302, a generally horizontal member 1304, and a connector 1306. The generally vertical member 1302 may be a new or existing post or wall or any portion of a new or existing structure. The generally horizontal member 1304 is rotatable about a generally horizontal axis and rotatable about a generally vertical axis to move the canopy support structure 100 in a desired orientation and position. The generally horizontal member connects to the generally vertical member with the connector 1306.

In some embodiments, the mounting connector 118 is connected directly to the first hub 102. In other embodiments, a different mounting connector (e.g. 506) may connect the horizontal member 1304 to the second or third hubs 104, 106. A mounting stop 804 may be used to provide a position stop and relative spacing between the second and third hubs 104, 106 to help define the fully extended position for the canopy support structure 100. A connection between the canopy support structure 100 and the generally horizontal member 1304 may provide a relative positioning between the canopy support structure 100 and the generally horizontal member 1304. In some embodiments, the generally vertical member 1302 may be able to rotate about a vertical axis.

FIGS. 14-16 illustrate the canopy support structure 800 (described above with reference to FIGS. 8 and 9) mounted to an alternative suspension support member 1400. The suspension support member 1400 includes a horizontal member 1404 and spaced apart vertical members 1406, 1408. The vertical members could be posts, walls, or other members providing vertical support (e.g., other horizontal members such as beams). The horizontal member 1404 may include a track feature to which the mounting connector 506 is connected. The track feature may permit horizontal movement of the mounting connector 506 along the length of the horizontal member 1404 to position the canopy support structure 800 at various lateral or horizontal positions. The vertical members 1406 may have height adjustable features so as to provide height adjustment of the canopy support structure 800. Such height adjustment features and track features may be included in any of the suspension support members disclosed herein. Alternatively, the suspension support member 1402 may include curved or sloping members (e.g., a gazebo frame).

The canopy support structure 800 is mounted to the suspension support member 1402 with mounting connector 506. The mounting connector 506 extends through at least the first hub 102 and is connected to one or the other of the second and third hubs 104, 106. FIG. 15 illustrates an arrangement in which the mounting connector 506 is connected to the third hub 106. The first and second hubs 102, 104 slide along the length of the mounting connector 506 as the canopy support structure 800 moves between the fully extended position shown in FIG. 14, the partially extended/partially retracted position shown in FIG. 15, and the fully retracted position shown in FIG. 16.

When mounting the canopy support structure 800 to the third hub 106 (also referred to as a bottom hub), the canopy support structure 800 maintains a fixed minimum height. Typically, the horizontal member 1404 must be positioned higher as compared to other suspension support member embodiments so as to provide spacing for the first and second hubs 102, 104 to move vertically upward as the canopy support structure 800 moves between the fully extended position shown in FIG. 14 and the fully retracted position shown in FIG. 16. When a canopy support structure is suspended from above by connection to the first hub 102, the second hub 104 move vertically downward and the third hub 106 moves vertically upward so as to shift at least portion of the canopy support structure vertically downward when moving between a fully retracted position and a fully extended position. Thus, the embodiment shown in FIGS. 14-16 provides a constant ground clearance arrangement for the canopy support structure while other embodiments disclosed herein provide a variable ground clearance arrangement. Ground clearance may also be influenced by the length of the ribs, in particular those ribs 108-b that extend from the secondary sets of hubs 802.

FIG. 17 illustrates another example canopy support structure 1700 that is mounted to a suspension support member 1702. The canopy support structure 1700 may include only second and third hubs 104, 106 as a set of primary hubs. The canopy support structure 1700 may also include a plurality of sets of secondary hubs 802 that each include a pair of hubs 1706, 1708. Various primary, secondary and tertiary ribs 108, 110, 112 may interconnect the primary and secondary hubs.

The canopy support structure 1700 is mounted to the suspension support member 1702 with mounting connector 118. Mounting connector 118 is connected to the second hub 104 of the primary set of hubs. A portion of the mounting connector 118 may extend vertically below the primary hub 104. The primary hub 106 may slide along a portion of mounting connector 118 during at least a portion of the movement of primary hub 106 that occurs between extended and retracted positions for the canopy support structure 1700. The mounting connector 118 may act as a guide and/or support for the primary hub 106 during some of its travel toward or away from the primary hub 104. In some embodiments, a distal portion of the mounting connector 118 may include a lip, ridge, or other feature that may act as a position stop to control travel of the primary hub 106 relative to the primary hub 104.

The mounting connector 118 may also include a canopy stop 1704. A canopy may be mounted directly to the canopy stop 1704 as opposed to resting on top of the primary hub 104. The elevated position of the canopy stop 1704 tends to provide a downward sloping orientation for the top surface of a canopy that is mounted to the canopy support structure 1700. This sloped orientation may assist in providing draining of water, debris, etc. off of the top surface of the canopy when the canopy support structure 1700 is in an open (fully extended) position. The use of canopy stop 1704 may be particularly helpful for drainage purposes when used with a canopy support structure that includes only primary hubs 104, 106 as opposed to other designs that include primary hubs 102, 104, 106. One advantage of such three hub arrangements is that it provides for support of the canopy on primary hub 102 at a position well above hubs 104, 106, thereby creating a sloped arrangement for the canopy. Another advantage of a three hub arrangement is that the ribs 108-a provide additional support for the frame, which allows lower hubs 104 and 106 to be drawn closer together, creating a flatter and more contemporary aesthetic. A further advantage of the three hub arrangement is that it may result in a more compact retracted structure.

An assembly of the canopy with the canopy support structure 1700 may be removed from the suspension support member 1702 (e.g., for storage, repair, etc.) by disconnecting the mounting connector 118 from the suspension support member 1702. The canopy stop 1704 may help contain the canopy in connection with the canopy support structure 1700 in this situation.

The connection point between the mounting connector 118 and the suspension support member 1702 may include, for example, a pivot connection. In some arrangements, the suspension support member 1702 may include a track feature to permit movement of the mounting connector 118 along at least a portion of the length of the suspension support member 120. The suspension support member 1702 may be part of, for example, any one of the suspension support members disclosed herein, such as being the horizontal member 1404 of the suspension support member 1400 described with reference to FIGS. 14-16.

FIG. 18 illustrates the canopy support structure 1700 supported by a gazebo style suspension support member 1800. The suspension support member 1800 includes a plurality of generally horizontal members 1802, 1804, 1806, 1808 and a plurality of generally vertical members 1810, 1812, 1814, 1816. The generally horizontal members 1802, 1804, 1806, 1808 may intersect at an intersection point 1818. The canopy support structure 1700 may be connected to the suspension support member 1800 at the intersection point 1818 or at any other location along any one of the generally horizontal members 1802, 1804, 1806, 1808. In some embodiments, a single suspension support member 1800 may support a plurality of canopy support structures.

The mounting connector 118 may connect the canopy support structure 1700 to the suspension support member 1800. The mounting connector 118 may be connected to either the second hub 104 or the third hub 106. The suspension support member 1800 may be used to support any of the canopy support structures disclosed herein, and the canopy support structures may be connected to the suspension support member 1800 using any of the first, second and third hubs 104, 106, 108 and any type of connecting member (e.g., mounting connectors 118, 506, etc.).

FIGS. 19 and 20 show the canopy support structure 100 of FIGS. 1-3 mounted to the suspension support member 1300 of FIG. 13. The mounting connector 118 used to connect the canopy support structure 100 to the suspension support member 1300 may include a plurality of position stop members 1902, 1904. The stop member 1902 may provide a position stop for the second hub 104 as it moves toward the third hub 106 during extension of the canopy support structure 100. The stop member 1904 may provide a position stop for the third hub as it moves toward the second hub during extension of the canopy support structure 100. The stop members 1902, 1904 may include, for example, a protrusion structure as shown in FIGS. 19 and 20. In other embodiments one or both of the stop members 1902, 1904 may include a ring shaped structure and may be depressible or adjustable in size, shape or location along the mounting connector 118.

In other embodiments, any one of the canopy support structures disclosed herein may be suspended from an overhead cable or series of cables. In one example, a mounting connector 118 may be connected directly to the overhead cable(s). Other types of support structures may be used to support one or more of the canopy support structures disclosed herein, such as a gazebo, a cantilevered beam extending from a building, a tree branch, or the like.

A draw member may be attached to hub 106 and extend through mounting connector 118 to an internal pulley system or a combination internal and external pulley system, such that pulling on the draw member extends the canopy and releasing the draw member allows the canopy to retract under its own weight. Alternatively, one or a pair of draw members—one each side of the mounting connector 118, may each be attached to hub 106, extend up through a pulley at hub 104, down through a pulley in the wall of mounting connector 118, and up to an internal pulley system or a combination internal and external pulley system. Other arrangements involving multiple pulleys are possible for more or less mechanical advantage.

The various draw members 114, 116, 404, 504 and pulleys 402, 502 described with reference to FIGS. 1-5 may be used with any of the other embodiments disclosed herein to assist in operating the canopy support structures between fully extended and fully retracted positions, or into various pivoted, rotated, or laterally adjusted positions. Other types of features and components may be used to operate the canopy support structure as disclosed herein as well as the various suspension support members, mounting connectors, and the like. Further, other types of structures may be used to mount a canopy support structure to a suspension support member from above (e.g., from a position vertically above the canopy support structure). In some embodiments, more than one mounting connector may be used to connect to one or more of the hubs of a canopy support structure to suspend the canopy support structure from above.

The various features, functionality, etc. disclosed herein may provide a number of advantages in the field of canopy and umbrella structures, particularly, a canopy support structure that is supported from above will remove the standard support pole that is typically used for supporting a canopy or umbrella. Such a support pole often is an obstruction and prevents use of the canopy or umbrella in certain applications such as at a fire pit, over open water, over a table, and the like. Furthermore, a support pole must be stabilized at its base in order to properly support the canopy or umbrella. By removing the support pole and positioning the support structure at a location spaced laterally from the canopy or umbrella, or even from a location vertically above using an existing structure such as a door frame, ceiling joists, or the like, the obstruction is removed and additional stability and support may be implemented for the canopy and/or umbrella. Further, by supporting the canopy or umbrella from above, it may be easier to adjust a vertical and/or horizontal position of the canopy or umbrella without having to move the supporting member itself, as is common when using a support pole.

The vertical and horizontal spatial relationships disclosed herein between, for example, the primary hubs 102, 104, 106, are exemplary only. Typically, the hubs 102, 104, 106 are arranged in series relative to each other. The axis of alignment of the hubs 102, 104, 106 may be oriented in any of a variety of directions, such as vertically, horizontally, or at some angle between vertical and horizontal. Generally, the canopy support structures disclosed herein may be arranged at any desired orientation when in the retracted and extended positions.

While illustrative and presently preferred embodiments of the invention have been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and are intended to represent a spectrum of design variations and versatility provided by the invention. The appended claims are intended to be construed to include such variations, except as limited by the prior art.
